APPLIANCE FOR HAND-TORCHES.

Specification of Letters Patent.

Patented Aug. 11, 1914.

Application filed October 20, 1913. Serial No. 796,281.

To all whom it may concern Be it known that I, JOHN A. Bowman, a citizen of the United States, and a resident of Sycamore, in the countyof Dekalb and State of Illinois, have invented certain new and useful Improvements in Appliances for HandTorches; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, whichwill enable others skilled in the art to which it appertains to make and use the same.

This invention has general reference to an appliance for hand torches.

It consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described and then pointed out in the claims.

In the drawing already referred to which illustrates my said invention more fully, Figure 1, is a longitudinal, vertical section of a typical hand torch showing my appliance in elevation, the dotted lines being employed to indicate the said invention in a different position upon the torch. Fig. 2 is a transverse, vertical section in the direction of the arrow pointers, in line 22 of Fig. 1. Fig. 3 is a partially exposed horizontal section in the direction of the arrow pointers in line 3-3 of Fig. 1, the remainder of the parts of said figure being in elevation. Fig. 4 is a transverse section of the flame or burner tube in line 4-4 of Fig. 3. Flg. 5 1s a segment of a fragment in line 55, of Fig. 5. Fig. 6 is a plan of a fragment of a sheet metallic blank employed in my invention.

Like parts are indicated by corresponding symbols or characters of reference in the drawing.

The object of this invention is the production of means whereby soldering irons and the like may be heated in any of the typical hand torches now upon the market, said means being so constructed that no change of the torch is required aside from slipping my appliance over the burner thereof and fastening the same by a thumb or similar screw. This device is a valuable adjunct for all artisans using a hand torch, because every worker employing such a torch as an article of his kit must frequently use a soldering iron. Such irons are now heated by holding the irons in front of the flame of the torch, a time and fuel-wasting proposition. With my appliance a workman may insert a soldering iron therein and then go about his business until the same is hot enough for use. Or the worker may employ two irons, using one while the other is being heated. And when it is understood that my device may be applied, to or removed from anyhand torch, by a mere twist of the hand Without any change to the torch itself, its practicability becomes self evident.

In the drawings, A represents the body of the usual hand torch. In the present in stance the top B is shown as drawn integrally with the body A, while a bottom'C, is crimped in position by a base flange 1), the whole when properly soldered, forms the tank F. In the top near one side thereof is formed an opening surrounded by a sleeve 1 having an external flange 2, said sleeve is both exteriorly and internally screw-threaded, the former to receive a jam nut 3, adapted to form a tight joint between the flanged portion 2 and the metal of the top B, and the latter to accept a finger actuated filling plug 4. Located vertically alongside the body A of the tankF, there is provided a hand air pump G, which at the same time serves as a handle for the tank and also provides means to create a pressure within said tank in a manner easily, understood. Conveniently in top 13 near the edge thereof and at a point usually directly opposite the combined pump and grasping handle Gr, there is formed an opening to receive an annular,

flanged sleeve 5, the lower end of which is exteriorly threaded. Fitted over the sleeve there is a jam nut 6 to form a tight joint between said fianged sleeve 5 and the opening in the top B provided therefor. The interior of sleeve 5 is internally threaded for the reception therein of a length of piping 7, the lower end of which extends into tank F to near the bottom thereof, while the upper extremity is fitted into a typical angular needle valve 8, the free end of which generally points slightly upwardly, as shown, and possesses at its open end an upwardly projecting tube 9. This tube has a series of peripheral perforations 10, is open ended and is termed the burner tube or flame tube. After the tank F has been filled with the required hydrocarbon fuel and a sufiicient atmospheric pressure created therein by maafter which an intense flame will issue from i the open end of the burner, the necessary amount of oxygen being supplied through the perforations 10. The article just de scribed is the ordinary hand torch in readiness to perform its usual functions.

My newly invented appliance comprises an integral sheet metallic plate 12, the blank of which is cut to such shape as to form a flat rectangular bottom 13, having parallel, bent up sides 18 and 13, whose upper edges atone end are of arcuate contour merging with the bottom 13 at the dotted bending line a. Blank 12 has lips 14 and along both sides, which lips are bent up along the dotted lines Z) and c at an interior width equaling the external distance between the sides 13 and 13 The said blank 12 is now bent up from the line a to form a cover for the sides 13 and 18 with the lips 14 and 15 closely embracing the same. The end of this cover 16 is coincident with the perpendicular edges 17 and 18 of the side walls 13 and 13 and, rivets 19 are passed through said side walls and lips let and 15 to firmly hold together the integral structure now designated S.

The bottom 13 and top 16 are'provided with openings 20 for exit of hot gases, and in said bottom, near the open end of the structure 5 is punched an oblong opening 21, which is provided for passage therethrough of a bracket 22, which is, internally bored so as to be a free fit over burner or flame torch 9 hereinbefore described' This bracket has two lugs 28 and 2a and rivets 23 and 24?; it is riveted to bottom 13 of structure S. The internal bore of bracket 22 is spaced at such a height that when burner tube 9 is passed therethrough, the bottom of said tube will rest upon the bottom 13 of the heater or structure S. The bottom of the bracket 22 is tapped and fitted for a thumb screw 25, by the manipulation of which the heater S may be secured to the burner tube 9 in any desired position, be it vertical or horizontal, or at any angle between.

While herein I have disclosed the most preferred form of construction, I reserve the right to make such changes and alterations therein which would suggest themselves to the skilled mechanic or permitted under the doctrine of mechanical equivalents.

Having thus fully described my invention, I claim as new and desire to secure to myself by Letters Patent of the United States 1. An appliance for a hand torch having a fuel tank and a burner tube extending outwardly and upwardly therefrom; a heating receptacle comprising a floor, roof and sides, the burner of said torch extending within said receptacle and adjustably fixed to the said floor thereof whereby the angularity of said receptacle may be varied.

2. An appliance for a hand torch having a fuel tank and a burner tube extending outwardly and upwardly therefrom; a heating receptacle comprising a floor, roof, and

sides, an internally bored bracket fixed to said floor, fastening means on said bracket cxteriorly of said receptacle, said burner tube being adapted to enter the bore of said bracket and to be maintained in position within said receptacle by said fastening means.

3. An appliance for a hand torch having a fuel tank and a burner tube extending out 'ardly and upwardly therefrom; a heating receptacle comprising a floor, roof, and sides, said roof sloping forwardly to said bottom, the burner of said torch extending into said receptacle along the floor thereof and fixed in position adjustably, whereby the angularity of said receptacle with respcet to said fuel tank may be varied.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses JOHN A. BOTVYER.
